Like.
It is pretty clear that you do not. You like your SI-based framework and think that it is more than it is. It really isn’t. ##E/B=c## is... -
KKim Gi Hyuk replied to the thread Undergrad What physical quantity has dimension [ML⁻³T⁻²] in electromagnetism?.Thank you, Dale, for the extended discussion. After 22 exchanges, I think our core disagreement is now clear, and I'd like to close my...

KKim Gi Hyuk replied to the thread Undergrad What physical quantity has dimension [ML⁻³T⁻²] in electromagnetism?.Do you consider dimensional analysis itself to be unit-system-dependent? Buckingham's π theorem identifies dimensionless groups that...

This is nonsense. The quantities don’t even exist outside of a system of units. They cannot be organized outside of the system of units...

I wrote some code some time ago that while computing numbers, also tracked dimensions. It was able to identify the units and flag...
